 106           Some builds may require a 'biarch' toolchain. This option

 124                   If you're specifying an addition target architecture,
 125                   you'll probably need to also provide options to make
 126                   the compiler use this alternate arch.
 127
 128                   For example, if you're building a compiler that can build
 129                   both powerpc and powerpc64 binaries, you'll need to
 130                   specify -m64 here.
